Throughout the world today there are thousands and millions of people who firmly believe in what is known as "Spiritism." Among those who thus believe are some of the brightest minds of the day–doctors, lawyers, judges, professors, etc., a class of people who would not be deceived by mere sleight-of-hand performances, or by hallucinations. These know that it is possible to communicate with beings of the spiritual realm, through the aid of spirit mediums, clairaudiants, clairvoyants, and the like–the modern wizards and witches. Few recognize that every one of these spirit beings who thus communicate with members of the race of mankind are of the demons, or fallen angels–evil spirits–whose sole aim and purpose is to deceive the members of the race by impersonating the dead, and representing that they are the spirits of the departed ones. The Sacred Writers certainly recognized the existence of the demons, and of the witches (spirit mediums) of their day.
